<h3>Answer:  sometimes true</h3>

=======================================================

Explanation:

The plane P can be thought of a perfectly flat ground. Now imagine a flag pole which represents line GH. If AB is drawn in chalk on the pavement, and this line AB intersects the base of the flagpole, then we've made AB and GH intersect. However, this example shows that GH is <u>not</u> on the plane P.

Is it possible to have GH be in the the plane? Yes. We could easily draw another chalk line on the ground to have it intersect AB somewhere. But as the previous paragraph says, it's also possible that GH is not in the plane.

Therefore, the statement is sometimes true

Answer:

Step-by-step explanation:

use these two equations

A: y = 15

B: y = 2r + 5

a) set the equations equal to eachother for your first answer

15 = 2r + 5

B) solve for r

15 = 2r + 5

10 = 2r

5 = r

after 5 rides the cost will be the same

Use unit multipliers to convert 123 pounds per mile to ounces per centimeter. There are 5,280 feet in 1 mile. There are 16 ounce
gregori [183]
A unit multiplier is a conversion factor of value 1 that we can use to convert quantities.
We want to convert 123 pounds per mile to ounces per centimeter. 
First, we are going to express the quantity to convert as a fraction:
123 pounds per mile=123 \frac{pounds}{mile}

Next, we are going to find our multipliers:
- We know for our problem that there are 5,280 feet in 1 mile, so our first multiplier will be: \frac{1mile}{5280ft}
- We also know that there are 16 ounces in 1 pound, so our second multiplier will be: \frac{16ounces}{1pound}
- We know that there are 12 inches in 1 foot, so our third multiplier will be: \frac{1ft}{12in}
- We know that t<span>here are approximately 2.54 cm in 1 inch, so our fourth multiplier will be: </span>\frac{1in}{2.54cm}

Now we can put all our multipliers together:
123 \frac{pounds}{mile} * \frac{1mile}{5280ft}*\frac{16ounces}{1pound}* \frac{1ft}{12in}*\frac{1in}{2.54cm}=0.01 \frac{ounces}{cm}

We can conclude that the answer is 0.01

The actual length of the rectangle below is 41 cm. Using the scale drawing below, find the actual width.
Margaret [11]

Okay, so your scale rectangle has a length of l = 8.2 cm. The actual triangle has a length of L = 41 cm. What is the scale factor? You find out by dividing the scale rectangle l from the actual rectangle L.

41 cm / 8.2 cm = 5

The scale factor is 5. That means the actual rectangle is exactly 5 times bigger than the scale rectangle. Now finding the width is easy! If the width of the scale rectangle is 2.1 cm and the scale factor is 5, you just multiply them together!

2.1 cmx 5 = 10.5 cm

The width of the actual rectangle is 10.5 cm! Hope that helps!
